For the drive to operate, one of the following field supply
options must be present.

A Fixed Field Supply

A Regulated Field Supply

An Enhanced Field Supply

At power-up if the Regulated Field Supply Card is installed:

1.

P.177 [Field Regulator]

will detect it’s presence and display

either 4, 10 or 20A — the Regulated Field Supply Card’s
rating.

2. The field current control loop shown above operates and

drive parameters P.184 [J20 Fld Loss Det], P.185 [J21 Field
Supply] and P.272 [E-Fld Volts Adj] are ignored.

3. The Regulated Field Loss and Field Economy circuits

become active in place of those used by the Fixed and
Enhanced Field Supply options.
